Watering New Zoysia Sod: Use a Soil Moisture Sensor

New zoysia sod needs consistent moisture to root, but a fixed schedule wastes water and can cause disease. The best approach: water only when the soil needs it.

Why a Schedule Fails

Rainfall, temperature, wind, and soil type all affect how quickly sod dries. A set schedule ignores these variables, leading to over- or under-watering.

Smart Irrigation Solution

Install a soil moisture sensor (like UgMO or Rain Bird SMRT-Y) connected to your irrigation controller. The sensor measures root-zone moisture and signals the system to run only when the soil reaches a preset dryness threshold. This saves water, prevents fungal diseases, and promotes deep rooting.

If a sensor isn't feasible, check soil daily by probing 2-3 inches deep. Water when the top 2 inches feel dry. Apply enough to wet the soil 6 inches deep (about 1 inch of water).
